• Insulation monitoring module for the Schneider Electric 4-pole Compact NSX 400/630. This module detects and displays insulation drop. When the insulator falls below the minimum value, the LED turns on and the auxiliary contact switches. Installed directly on the device terminal. This isolation monitoring module is internally self-powered by the voltage of the power distribution system and can be powered from as few as two phases. There is a Class II isolation level between the front and the power supply circuit. IP Protection Grade - IP40 Mercury-Free
